Adobe Desktop Technologies Ascend to the Cloud
Adobe Photoshop is the premiere desktop tool for editing images. It offers the most powerful algorithms for image processing available anywhere, and is loved by creative people around the world. Not only is it ubiquitous in design shops, it is also used by companies (like ourselves) who generate dynamic content with it.
Photoshop is well-exposed to automation: it has actions that are easy for non-developers (yet quite powerful), and it also supports ExtendScript, as well as C++ and CEP (Adobe's Common Extensibility Platform). XMPie is a company that has actually built a product, uImage, that runs Photoshop desktop like a server to produce one-to-one marketing pieces.
Until now, the Photoshop rendition engine has only been available through the desktop application. However, Adobe has just announced the pre-release program for Photoshop as a Service.
